Music from Led Zeppelin has been made available for pre-order on the iTunes Store.
Two albums are available now, The Complete Led Zeppelin, consisting of 141 classic tracks plus the new collection, Mothership (remastered). Both albums are expected to be made available on 12 November, according to a note on the store.
To mark the moment music from one of the last digital music holdouts appears online, Led Zep fans pre-purchasing either collection will automatically be entered into a competition to receive two tickets to the band's sold-out show at the O2 Arena on 26 November. They will also receive two tickets to a private dress rehearsal the night before the gig, and three nights hotel accommodation in London.
Apple has also made two new television series available through iTunes: comedy show The World Stands Up and Fairly OddParents.
This week's free download comes from rapidly emerging act, The Hold Steady.
